Ordered mine (27", 2.93GHz i7, 2TB, stock RAM) yesterday and should get it in a week or so.
Last time I used a Mac was my roomie's original MacIntosh, circa 1984, so I suspect I got a few surprises in store with this one!
I do know Unix really well so I'm hoping that will help me on the admin side of things. Going to do a RAM upgrade myself ... just have to google for some good instructions on how ... there seems to be a lot of different types of memory out there.
Already have a Dell 27" monitor (U2711) so I've ordered a mini-displayport to displayport cable to run it side-by-side on the iMac. Whaddya think? Dual 27's got enough screen real estate? LOL!
Wish this Mac newbie luck... I got me some learnin' to do...
Welcome to the family and good luck with the switching.
My i7 will land this week so I'm not too envious.. but I do like the sound of that second 27" display... aaargh!
